Penetration Testing
Find the breach before an attacker does.
Zarsco's penetration testing team manually attacks your applications, networks, and infrastructure the same way a real adversary would — chaining vulnerabilities, escalating privileges, and proving business impact instead of just listing CVEs from a scanner.
Manual, Human-Led Testing
Certified testers manually exploit and chain vulnerabilities — automated scanners alone miss critical business logic flaws.
Business-Impact Focused
Every finding is mapped to real business risk, not just a CVSS number, so you can prioritize what actually matters.
Full-Stack Coverage
Web, mobile, API, network, and cloud infrastructure tested under one unified methodology.
Free Retesting Included
Once you remediate, we retest affected findings at no extra cost to confirm the fix holds.
What we do for you
Web Application Pentest
OWASP Top 10 aligned testing of authentication, authorization, and business logic.

Cloud Infrastructure Pentest
AWS, Azure, and GCP configuration review combined with active exploitation attempts.
Mobile App Pentest
iOS and Android testing covering insecure storage, API communication, and binary analysis.

Frequently Asked Questions
What is the difference between a vulnerability scan and a penetration test?
A vulnerability scan is automated and flags known signatures. A penetration test is manual — our testers actively exploit findings, chain them together, and demonstrate real business impact that scanners cannot detect.
How long does a penetration test take?
A focused web or API pentest takes 5–10 business days. Larger scopes covering networks, cloud, and multiple applications typically run 2–4 weeks.
What will I receive at the end of the engagement?
A detailed report with an executive summary, technical findings with proof-of-concept and CVSS scores, and prioritized remediation guidance — plus a live debrief call to walk through results.
Can you test our production systems safely?
Yes. We agree on safe testing windows, exclude destructive test cases unless explicitly requested, and coordinate closely with your team to avoid any service disruption.
